Abstract
The laminar, natural convection flow adjacent to a vertical isothermal surface in viscous oils is analyzed. The strong variations of viscosity with temperature is represented by an exponential function. Similarity solutions are found to exist. It is shown that for a heated wall the constant viscosity results underestimate the Nusselt number and overestimate the drag coefficient. For the cooled wall, the opposite is true. The heat transfer results for the heated wall are in very close agreement with the corresponding correlation of previous experimental investigations. A new correlation for the cooled wall is suggested.
